EXTENSIQN OR PULL-OVER BED.

Application filed March 2 1, 1924. Serial No. 700,854.

My invention has relation to improvements in beds and 1S dlrected more part1cu-' larly to combination day-beds and couches, .and consists in the novel features of construction more fully set forth in the specification and pointed out in the claim.

The object of the present invention is to provide a day-bed having two superposed sections the u er of which Ina be swung outwardly and downwardly to a position adjacent toand in thesaine plane with the lower section to form a couch of twice the width of the normal day-bed. A further object is to provide a combined day'bed and couch of rigid though siniple construction, and one having suitable space between the superposed sections for the bedding.

parent from a invention in connection with the acco1n panying drawings, in which Figure 1 is a top plan of my improved, bed with the sections in extended position to form a couch, parts being broken away; Fig. 2 is an end elevation of the bed in ex tended position; Fig. 3 is a side elevation of the extended bed; Fig. 4 is an enlarged end elevation of the bed with the sections in superposed position to form a day-bed; and Fig. 5 is an enlarged side elevation of the corner piece on the detachable head and foot pieces that cooperates with a complementary corner piece on the legs of the bed; Fig. 6 is a modified form of the invention.

Referring to the drawings A and B represent the respective bed sections, the former the main supporting section and the latter the swinging or pull-over section connected in parallelism to the main section by two pairs of links to more fully hereinafter appear. The main section A is provided with legs 1, 1 at each end thereof, to the upper ends of which is secured an end rail 2 a short distance below which the legs are connected by an angle bar 3, and across the corners between the legs 1 and end rail 2 are suitable brace members 4, 4. A side rail 5 is secured to and connects the legs 1, 1 on Fur r ther and other advantages will be better apdetailed description of the each side of the main section A, said side rail being disposed in a plane slightly below the end rails 2, 2. A =-link fabric 6 is stretched between the end rails 2, 2 to which it is secured by a plurality of helical springs 7 as Well understood in the art.

Thepull-over section B is provided with legs 8 and 8 at each endthereofQto the upper ends of which is secured an end rail 9, and across the corners between the legs.

8,8 and end rail 9 are suitable braces 10, 10. It will be observed (Figs. Q'and 4) that the legs 8, 8, which are onthe saine.

side of section B, are of the same length as legs 1, 1 of section A, and legs 8 8, also on thesaine side, are considerably shorten The reason for this will be readily apparent in the description of the operation of the invention. Legs 8, 8 are connected by a side rail 11, and legs 8, 8 are connected b a side rail 12. A link fabric 13 is'stretcl ied between end rails 9, 9 to which it is secured by a plurality of helical springs 14;, 14-- The section B is connected to sectionA in parallelism by a pair of. links 15, 16" at each end of said sections. Each linkl5 is pivotally connected-to an angle bar 3 at.

which are secured the inner ends, of a pair of balance springs 19, 19., the. opposite ends of said'springs being secured to side rails 5, 5 of the main section A. The links 16, 16 are also pivotally secured to bar 3 and end rail 9 in parallelism with links 15, 15 although links 16 are bent so as to clear the inner side rail 5 when the sections are.

extended (Fig. 2).

When the sections A and B are in superposed position to form a day-bed (Fig. 4) it will be observed that the legs 8, 8' of section B rest on end rails 2, 2 of section A and legs 8, 8 rest on angle brackets 20, 20 secured to adjacent legs 1, 1, and at the same time the springs 19 on the side toward which section B must be moved to extend it are under tension, which will assist the operator in extending the bed. Now as the section B is pulled up over section A the tension on the springs 19 will become balanced as the section B is balanced on links 15 and 16. Just as soon as section B is lowered past dead center tension will be placed on the opposite springs 19 to counter balance the Weight of saidvsection and this counter balancing spring tension will again be at its maximum when section B is lowered to the floor (Fig. 2). When the section B is fully extended its legs 8, 8 will rest on the floor and the inner side of said section will be supported in the same plane with section A by the links 15' and 16.

It will also be observed that when the sections are superposed (F 1g, 4:) there is cone erable space between them, the purpose of which is to receive the beddingwhieh is folded over onto the main section before the pullover section is swung up.

If desired a back-rest 21 may be pivot ally mounted at one end of section B, said back-rest being provided with its own fabric' 22, and being adjustable bymeansof a U-shaped brace 22 the cross-bar 23 of which is adapted to-re'st in anypairof a series of notches n formed in Z ba'rs secured t the sides of side rails 1l and 12.

The entire tea may also bes upported by special headand foot pieces 24 and 25 respectively (shown dotted, Fig; '3) if desired, suitablecorne'r fasteners being provided for 7 this purpose on the legs 1, 1 e the main sec tion A. Each corner fastener 26 consists of an angle bracket26 riveted to the leg llrem the outwardly projecting portion 26' of which bracket are two-spaced pins 27, 27 provided with enlarged heads 28, 28. The fasteners 26, 26 are adapted to cooperate with fasteners 29 29 on the posts of the head and foot end,'said fastenersconsisting' of angle brackets each having its inwardly projecting portion 29 provided with a "slot 30 open at the upper edge of thebracket and a; slot 31 below the slot 30, the slot elneving a terminal enlargement 32. V I k In mounting the bed on thehead (and feet pieces 24,, 25 each end is raised te-permit the heads 28 of the lower pins 27, to enter the enlargement 32 of slot 31, after which 7 sections A and the pins27, 27 are 'droppeddown into slots 30 and 31. The portioni29 of bracket 29 adjacent the slots 30, 31 is then wedged between the portion 26 of bracket 26 and the heads 28 of the pins'27 to hold the-bed and the head end foet pieces in firm engagement.

Referring now to Figure 6, it will be observed thatthe link 16 has connected to it a short link 33, said link 33 also being pivotally eonneeted at 37' to the end rail 3 between the points of connection of links 16 and 15. A bracket rest 34 is fixed to the rail 3just'be1owthe point er eeml'eetien er links 16am 33, (when said links are in normal position) the purpose of which rest is to ipped the link 16 as, it. swings outwardl in extending section B. A stop pin 35 is secured in the rail 3 ju'stbehind point y. Now, in order to make the space between B mere eeeeeible for bed clothes, section B may be tilted upwardly (dotted,Fig.'6) the 1inks16and 33 assum ing a position; shown by the dotted lines and being arrested by'the pin 35 which holds the sectionB in this position until manually ii dv v 1 Having described my invention, '1 claimi A bed composed of two sections, one of said sections constituting a main or sup-r porting section andithe other an extension section, the latter being normally supported abovethe main section and in spaced relation therewith, and being movable through an arc to a position adjacent to and in the same plane with the main section, means for maintaining'said extension section in parallelis'm with the main sectionthfou hoiit its entire arc of movement, and said last mentioned means being arranged to permit tilting said extension section upwardly in a irection opposite to that'in'whieh it moves when extended.

v In testimony whereof I hereunto afiix my signature.
